Please note this is NOT a battery. It is a battery holder. It provides a 7.4V nominal voltage for use with existing Fat Shark goggles and fits into head strap like standard Fat Shark battery packs. Large capacity when used with high capacity cells (batteries not included). We're told that these are readily available at stores selling e-cigarette and vape accessories.

Batteries should be removed and charged via a dedicated 18650 style charger.
